B4J Question Java JDK19

[Beja]

Hi all,
Today I installed JDK 19 and when I tried to compile an old project I got this error message:

^
1 error

Any meaning appreciated

JDK 11 provided here in the forum has the javafx module.

Since that version of java. JDKs doesn't have javafx included as default.

You have to install javafx manually.

Don’t use JDK 19. It’s a short term release and support ends in a few months time.

Use 11 or 17.

OpenJDK 17 or 19? JavaFX SDK 17?

I understand that the recommended version for B4J (current version 9.80) is OpenJDK 11. Should I combine javafx17 with openjdk17? Or can I leave open jdk11? Better to use jdk11 or 14. https://www.b4x.com/android/forum/threads/update-openjdk.140167/ Note that you can use any version of...

Although I have to say that I have the JDK version and JAVAFX version 19.0.2 installed, and I have not had any problems.

Yes, but small possible.
@Beja check this topic about installation 19: https://www.b4x.com/android/forum/threads/openjdk-17-or-19-javafx-sdk-17.145853/
But seems, useless now.

In the output I can see

src\b4j\example\main.java:128: error: package javafx.scene.image does not exist

I guess you use a JDK which does not have JFX. Either you use the JDK package from B4X or you should use a JDK which contain JFX.
E.g. I use the openjdk from Azul. On the download page I have to select the Java version and the content (with JFX or without).
Look here.

I agree with the comments before to use a LTS version, 11 or 17.

Yes you won’t have any problems compiling but there won’t be any more updates to JDK 19 in a few months. No security fixes, no bug fixes etc.

Given Javas security reputation do you really want to give your users an unsupported version of the JDK?

Dear, I'm just testing the new versions of java.
For production applications I use Java 11 or 17.

I just use 19 for trying out the new features like virtual threads etc.
It works in debug, Release and Packager fine.
